I need to replace a lot of plain text with italicized text. Can’t figure out how to do it?

I have a lot of titles that I've set in bold and need to be changed to italicized:

For instance: Let's say the book title was Romance and I want to change every instance of this title to Romance.

I've tried copying an italicized version of the word into the "replace" box, but it won't "take." The box remains empty.

Is there any way to do a search and replace when you want to change a word to an italicized word?
